Problems solved by technology
At present, there is no special reflector for laser processing on the market. If only simple shielding is used in production, it will not be able to fully shield the reflected light.
Ordinary lamp reflectors do not have laser beam holes, and cannot be directly installed on the laser
Since the laser is different from sunlight and ordinary light in terms of wavelength, its production materials have higher requirements, and must maintain high reflectivity at the laser wavelength. In addition, due to the ultra-high power of the laser and the long processing time of laser processing, this reflection The cover will absorb a large amount of photon energy. If there is no special cooling design, the reflector will be damaged and lose its role of safety protection

Abstract
The invention relates to a special water-cooling reflecting cover for laser processing, belongs to the technical field of laser processing, aims to overcome the defect of no special reflecting covers for laser processing in the conventional market, and provides a novel and special water-cooling reflecting cover for laser processing. The water-cooling reflecting cover comprises a reflecting cover upper part and a reflecting cover lower part, wherein the reflecting cover upper part comprises a reflecting cover upper part main body, a water-cooling water inlet, a laser beam through hole, an internal thread interface, screw holes, an external sealing ring groove upper part, an internal sealing ring groove upper part and a water-cooling groove upper part; the reflecting cover lower part comprises a reflecting cover lower part main body, a water outlet, a laser beam through hole, screw holes, an external sealing ring groove lower part, an internal sealing ring groove lower part and a water-cooling groove lower part; the reflecting cover upper part and the reflecting cover lower part are both in shapes of an arc with camber, and are connected with each other through bolts. The water-cooling reflecting cover can effectively cover the processing region in the laser processing process, and fully absorbs reflected laser; meanwhile, a water-cooling system can prevent the water-cooling reflecting cover from overheating, and guarantees safety of the personnel and devices nearby.
Description
technical field [0001] The invention belongs to the technical field of laser processing, and in particular relates to a special water-cooled reflector for laser processing. Background technique [0002] In laser processing, the processed material cannot completely absorb the laser energy, and its surface will reflect a part of the photon energy to the surrounding space. Due to the enormous power of the laser, this small amount of reflected energy could still injure the operator or damage peripheral equipment. At present, there is no special reflector for laser processing on the market. If only simple shielding is used in production, it will not be able to fully shield the reflected light. Ordinary lamp reflectors do not have holes for laser beams, and cannot be directly installed on lasers. Because the laser is different from sunlight and ordinary light in wavelength, its production materials have higher requirements, and must maintain high reflectivity in the laser wavele...
